Rules for Dating Trash: Character Guide & Story Setup

Rules for Dating Trash is a completed romance webcomic centered on Ihyeon Seon, a college student returning after a three-year break caused by a messy breakup. Her goal is simple: complete her senior year without attracting more attention. That plan quickly falls apart when her ex reappears and Chanu Nam, a campus bad boy, begins showing a persistent interest in her.

The series combines romantic comedy with a deliberately chaotic relationship setup. Ihyeon is not immediately searching for a new partner, while Chanu approaches her with the confidence of someone accustomed to attention. Their opposing intentions create the main tension: the more Ihyeon tries to create distance, the more Chanu seems determined to remain in her orbit.

The official Rules for Dating Trash WEBTOON page classifies the series as Romance, credits Seo Yeon as its creator, and notes its Young Adult 16+ rating.

Video Highlights:

• Ihyeon’s difficult return to college shapes the opening conflict.
• Campus forums intensify the rumors surrounding Ihyeon and Chanu.
• Chanu’s playboy reputation contrasts with his growing attention toward Ihyeon.
• The ex’s return leaves important parts of Ihyeon’s history unresolved.

The cast is introduced through reputation as much as through direct interaction. Ihyeon is known around campus for the story surrounding her breakup, while Chanu is recognized as a womanizer and bad boy. These labels influence how other students interpret their behavior, often before either character has a chance to explain themselves.

Ihyeon’s characterization is built around discomfort, guardedness, and the desire to regain control. Returning to college at twenty-five places her in an environment where gossip travels quickly. Her reactions to Chanu and her ex are shaped not only by attraction or anger, but also by the fear of becoming the subject of another public narrative.

Chanu initially presents himself as confident, provocative, and emotionally difficult to read. He can be dismissive in one scene and attentive in the next. That inconsistency is part of his appeal as a romantic lead, but it also creates a major question for the story: is his interest genuine, or is he treating Ihyeon as another entertaining challenge?

The central romance works because Ihyeon and Chanu begin from opposing positions. Ihyeon is reluctant to enter another relationship, particularly when her previous one has already affected her education and public image. Chanu, meanwhile, appears comfortable with flirtation and attention. His behavior creates immediate chemistry, but it also gives Ihyeon valid reasons to remain cautious.

Their repeated encounters provide the series with a strong romantic-comedy rhythm. They meet in classes, around campus, and during uncomfortable social moments. Each encounter pushes Ihyeon toward a decision: ignore Chanu, confront him, or allow the relationship to develop on his terms. Chanu’s persistence keeps disrupting her attempts to stay uninvolved.

A major source of tension is the contrast between public labels and personal choices. Ihyeon is treated as an object of gossip because of her past, while Chanu is treated as a familiar type because of his reputation. Both characters are therefore pressured to perform the roles assigned to them. The romance becomes more interesting when their direct interactions begin to complicate those assumptions.

Rules for Dating Trash benefits from reading with attention to social context. Early scenes introduce Ihyeon’s reputation before fully explaining the event that created it. This makes the opening feel intentionally one-sided: readers see how people talk about her before they understand what she experienced.

The first major checkpoint is Ihyeon’s encounter with her ex after returning to college. His appearance immediately disrupts the stability she is trying to create. The next checkpoint is Chanu’s introduction as a separate source of tension. His reputation is widely discussed, but Ihyeon’s direct experiences with him are more complicated than the campus label suggests.

Another important checkpoint is the development of a shared academic environment. Classes and campus routines reduce the distance Ihyeon wants to maintain. Chanu gains more opportunities to speak with her, while the ex remains a visible reminder of the past. This structure allows the romance and mystery plots to advance together.

Seo Yeon is credited as the creator of Rules for Dating Trash. The official creator profile describes an interest in romantic comedies and heartwarming illustrations, which matches the series’ combination of uncomfortable situations, heightened chemistry, and emotionally charged humor.

The story’s strongest theme is the conflict between personal identity and public reputation. Ihyeon is not allowed to return quietly because other students have already created a version of her past. Chanu faces a similar problem from the opposite direction: his bad-boy image makes his sincere actions difficult to believe.

The series also explores emotional recovery. Ihyeon’s return to school represents an attempt to reclaim a path interrupted by heartbreak. Her romantic choices are therefore connected to independence, confidence, and the right to define her own story. Chanu’s development depends on whether he can move beyond flirtation and demonstrate that his interest deserves trust.
